PACKAGING STRIP Filed June 17. 1949 INVENT MART|N VAN ANT RPEN A'FI'O NEYS ?a.tented July 15, 15952 1 -This invention appertains to packing and shipping of, fragile articles, such as automobile'window glass.

. One of. the primary objects of the invention is to provide. a cushioning and shock absorbing packaging strip for engaging and supporting the edges of a group of glass plates or sheets in a shipping carton, whereby the sheets willbe eifectively held and protected against breakage.

Another salient object .of the invention is to provide a packaging strip which merely includes an outer carrying or base strip formed from fiat material, such as fiber board, and an inner strip preferably formed from double corrugated board, secured to the base strip and having U-shaped, outwardly projecting spaced portions provided with notches for receiving the glass to prevent lateral shifting thereof, the material from said notches being bent in overlapping relation toward the base strip to form cushioning seats for the edges of the glass.

A further object of the invention is to provide cushioning pads of corrugated board or the like under the folded in portions to provide additional shock absorbing members for supporting the glass.

Another further object of the invention is to provide a cushioning strip of such a character, that the same can be readily folded and bent around the corners of cartons to effectively protect the corner edges of sheets of glass.

A still further object of the invention is to provide a packaging and cushioning strip of the above character which can be placed upon the market and fabricated at a small cost.

With these and other objects in view the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described and claimed and illustrated in the accompanying drawing, in which drawing,

Figure 1 is a side elevational view showing the packaging and cushioning strips in use for holding a group of sheets of glass in a carton, the carton being shown in section. I

Figure 2 is a top plan view of one of the packaging and cushioning strips.

Figure 3 is a top plan view of the blank of the corrugated board before the folding and gluing thereof to the base strip.

Figure 4 is an enlarged transverse sectional view through the packaging strip taken on the line fi4 of Figure 2, looking in the direction of the arrows, the sheets of glass being shown in dotted lines.

Figure 5 is an enlarged transverse sectional 2 Claims. (01. 206-62) view through a packaging strip taken on the line 5-5 of Figure 2, looking in the direction of the arrows, showing the glass in dotted lines,

Referring to the drawing in detail, wherein. similar reference characters designate corresponding parts throughout the several views, the letter 8 generally indicates the packaging and cushioningstrips for holding a group of'glass plates G in a shipping carton C. 1

The carton C forms no part of the present .in-

vention and can be considered as of a type now generally found on the openimarket for shipping flat articles. As shown, however, the carton C includes longitudinally extending side walls 6 and end walls 7 The cushioning strip S can be in a continuous length for extending entirely around the periphery of the glass plates G and between the glass plates and the side and end walls of the carton, or of a series of short length as illustrated in the drawing. Each strip S includes a base8formed from a fiat length of material such as fiber board, and an inner length of material 9, preferably formed from double corrugated board. The double corrugated board can be of the type ineluding inner, outer and intermediate facing sheets H3, and corrugated liner sheets H, between the inner and outer and intermediate facing sheets It. The inner corrugated board 9, is secured at spaced points to the base strip in any preferred way, such as by the use of an adhesive. In the formation of the cushioning and packaging strip S, the corrugated board 9 is of a greater length than the base 8, due to the fact that the corrugated board 9 is folded into a certain novel form, before its attachment to the base 8 by the adhesive.

In forming the inner corrugated board 9 for the fabrication of the strip S, the same is weakened along intermediate parallel lines [2 on opposite sides of the transverse center thereof and by parallel weakening lines I3 adjacent to the opposite ends thereof. Between theweakening lines l2 and [3, the inner corrugated board 9 is slotted by parallel slots I 4, which terminate short of the weakening lines l2 and 13. The material between the slots I4 is slotted transversely, as at I5, at a point intermediate the ends of the parallel slots M to provide tongues I6.

The strip is alsopreferably weakened by score line I! on its under face. These score lines I! extend tranversely of the inner corrugated board 8 and are arranged in spaced parallel relation and between the score lines l2 and I 3 on opposite sides of the transverse slot [5.

As is clearly shown in Figure 5, the corrugated board 9 is bent, by suitable machine, to provide outwardly projecting substantially U -shaped pro- :lections IS on the score lines l2, l3 and H. The inner face of the corrugated board 9 between the U-shape projections l8 and beyond the U-shaped projections are the portions of the corrugated board 9 which are united to the base 8 by the suitable means, such as an adhesive.

The tongues l6 are folded inwardly one upon the top of the other, within the U-shaped projections l8, as is clearly shown in Figure 5.

The formed strips s are placed around the edges of the group of glass plates G, as is clearly shown in Figure 1 and the edges of the glass fit within notches 19, defined by the folding in of the tongues I6. This prevents lateral shifting of the glass plates relative to the cushioning strips and the edges of the glass sit against the folded in tongues which form a cushioning support therefor. If desired, cushioning pads 20 can be placed between the base 8 and the tongues I6 to form an additional support for the glass plates. As is clearly shown in Figure 1, the cushioning strips fit between the Walls of the carton and effectively brace the carton and hold the glass plates centrally within the carton. The strips can be easily bent around the corners of the carton on the score lines l2, and there will be a U- shaped projection on each side of the corner of the groups of sheets of glass.

From the foregoing description, it can be seen that I have provided a simple cushioning and packaging strip for sheets of glass which can be economically fabricated.

Changes in details may be made without departing from the spirit or the scope of the invention, but what I claim as new is:

1. A packaging and cushioning strip comprising a base ply of sheet material, an inner ply of corrugated board secured to the base ply at spaced points having inwardly projecting substantially U-shaped portions between the points of securement of the inner ply to the base ply, said U-shaped portions being provided with longitudinally extending notches for receiving the edges of the material to be protected, tongues joined with the inner ply arranged in over-lapping relation and disposed in the U-shaped portions at the bases of the notches defining seats, and cushioning pads of corrugated board arranged in said U-shaped portions between the base ply and said tongues.

2. A packaging and cushioning strip adapted to be placed about the edge of a sheet of plate glass comprising a longitudinally extending base ply and a longitudinally extending inner ply secured to the base ply at spaced points having inwardly projecting substantially U-shaped portions between the points of securement of the inner ply to the base ply, said U-shaped portions being arranged in longitudinal alignment and being provided with longitudinally extending notches, said notches being also in longitudinal alignment for receiving the glass to be protected, and tongues joined with the inner ply arranged in over-lapping relation and disposed in the U- shaped portions at the bases of the notches defining cushion seats for the marginal edge of the glass.
